Earlier this year I updated my Apple Certified Technical Coordinator to the latest version of OS X. Lion came out in the sumer of 2011 and days after I took the ACTC update test OS X 10.7.3 was released. 10.7.3 was a huge improvement to Lion. In fact I’d even say that the differences between 10.7.2 and 10.7.3 would confuse a lot of people taking this test depending on which version applied to the questions. The ACTC applies to Server.app and basic OS troubleshooting. Recently Apple announced that they were going to a 12 month development cycle for “Major” OS releases. In reality big mid-release cycle updates are now going to be in the form of a $20 App Store download. Unfortunately for support staff and developers this will complicate life. For example, this ACTC 10.7 certification will only be 6 months old when OS X 10.8 is released. OS X 10.7 might not even get past a ‘10.7.4’ update. By comparison both Leopard (10.5) and Snow Leopard (10.6) were well into updates before being replaced (10.5.8/10.6.8).
